Rolls-Royce signs deal to trial hybrid-electric train conversions

LONDON — Rolls-Royce has signed an agreement to conduct a trial conversion of diesel trains to hybrid-electric engines in Britain, in a deal which could be rolled out to hundreds of trains across the country starting in the 2020s. The British company, which is best known for making aircraft engines, said on Wednesday that its German Power Systems business had signed an agreement with Porterbrook, the UK's largest owner of passenger rolling stock. Rolls-Royce's Power Systems unit, which sells engines used on ships, yachts, trains, trucks, mining and nuclear power stations, is one of the fastest growing parts of the company, and its boss said hybrid technology is behind that. "We expect hybrid technology to grow at above the current growth rates of diesel," the CEO of Rolls-Royce Power Systems, Andreas Schell, told Reuters. The Power Systems business is expected to post low double-digit revenue growth this year and is a bright spot in a company grappling with the negative headlines and cost of fixing a problem with its Trent 1000 aero-engines. Diesel trains can be fitted with Rolls-Royce Hybrid PowerPacks to turn them into hybrid trains that can also run on battery power, reducing carbon emissions and making them cheaper to run for operators while also making them much quieter when, for example, they approach stations. From RR's press release: The MTU Hybrid PowerPack is an environmentally friendly drive system which combines the advantages of diesel and battery-powered rail traction. The version for Porterbrook incorporates an MTU diesel engine which fulfils future EU Stage V emissions regulations; plus an electric machine, which can be used either as an electric motor or generator; and an MTU EnergyPack battery system, which stores the energy recovered during braking. This enables very low-noise, emissions-free battery-only electric operation in urban areas and around stations. The hybrid initiative comes as Britain seeks to phase out diesel-only trains by 2040. Adding the powerpacks to trains allows railway networks to be partially electrified without the need for expensive overhead infrastructure. The Institution of Mechanical Engineers says that 42 percent of Britain's rail network is currently electrified, which means that the country lags behind electrification rates in other European nations. Last year the British government scrapped electrification projects in some parts of the country, saying it would look to hybrid technology trains instead.

2021 Rolls-Royce Ghost has a fascinating new part to make it one of the most comfortable cars in the world

One of the neat things about Rolls-Royce is the extraordinary lengths the company will go to for maximum comfort. It's like how supercar builders will look for every little advantage to make their cars a tenth of a second faster. On the 2021 Rolls-Royce Ghost, the company is employing something called the Planar Suspension System, a nebulous designation for the collection of systems and parts employed. Some are straight forward, such as the four-wheel independent air suspension, and the way the GPS and forward cameras inform what level of firmness should be employed on the road. But one part left us perplexed: the upper control arm damper. We spoke to Jon Simms, lead engineer for the Ghost, for more information, and now we have a better grasp on what it is and what it does. As for what it is, it's the roughly horseshoe-shaped object highlighted in purple in the above photo. The yellow parts are bumpstops, and it's mounted on the same joint as the upper control arm. And it turns out it's a pretty simple piece of equipment. It works very much like the harmonic balancer on the end of an engine. It's a weight with a rubber-y flexible hinge, and going over smaller bumps, it absorbs some of the extra vibration and movement from the suspension. Those bumpstops in yellow give the damper some extra purchase on the control arm, and they absorb impacts from larger bumps that may move the control arm suddenly so that the arm and damper don't bang into each other. This may seem like a pretty minor thing, but remember, Rolls-Royce and its buyers are out for maximum comfort, so there's reason to invest in ironing out every possible ride quality issue, no matter the size. And even if it's a minor improvement, that's not necessarily a bad thing. Simms told us that existing Ghost customers they talked to during development had one key request about the driving experience: "don't break it." So making sure that the new car was basically like the last one, but a bit better, would seem to be what customers would want. 2021 Rolls-Royce Ghost View 29 Photos The Ghost is the first Rolls-Royce to adopt this full suite of Planar Suspension System parts, though other Rolls-Royce models have had pieces of the system. And considering the fact the Ghost shares its platform with the Phantom and Cullinan, now, we wouldn't be surprised if later versions of those models pick-up parts like this damper. Related Video:

The latest Rolls-Royce concept is a hybrid dump truck

Is a standard Rolls-Royce not big and imposing enough for you? Perhaps the company's latest concept can get you to pass the Grey Poupon. Behold, the Rolls-Royce MTU hybrid haul truck. The Cullinan might come with 22-inch rims, but when equipped with its R63 Michelin XDRs, each wheel and tire combo of the ultimate Roller will stand over 13 feet tall. With a driver's seat a full story off the ground, it's so lofty you won't even see the plebes that you crush in their feeble Coachbuild Dawns as indifferently as Loxodonta africana steamrolls a line of ants. Serve as your own life-size Spirit of Ecstasy as you look down at the puny Parthenon radiators of run-of-the-mill Phantoms from atop your soaring grille, located a full flight of stairs above the lowly earth. All jokes aside, the Rolls-Royce truck mainly serves to promote its new MTU V12 2000-series industrial 12-cylinder engines. Rolls-Royce doesn't even produce the haul trucks; typically, they provide the engines for installation into rigid dumpers built by Liebherr, Hitachi, or Selex. The new hybrid mill produces 1,560 horsepower, meant to replace the V16 4000-series 16-cylinder engines making 2,500 horsepower. However, Rolls-Royce says performance will be the same while dropping carbon dioxide emissions by 30 percent in new installations, or 22 percent with retrofits. Like a Prius, the engine uses a battery pack to store regenerative energy captured as the trucks descend into quarries, then expends that juice to climb back up. It also requires no additional space for an exhaust gas treatment system or diesel urea additives, which are apparently concerns in a mining truck. In addition, Rolls-Royce is in the process of engineering its industrial engines to run on sustainable fuels such as hydrogen brewed from renewable energy (not the way we do it in the U.S.). The company hopes to have hydrogen fuel engines ready by 2023 in stationary applications. It's all part of the company's goals for a — say it with us — carbon-neutral future. The concept truck was conceived for MINExpo 2021, a mining convention taking place September 26-29 in Las Vegas. Hopefully they'll put it into production and offer a constellation headliner in the cab.
